Application tiled January 25. 1.900. Serial No. 2,7'28'. .llo moaein' Toall whom it may coboern:

Be it known that I, FRITZ NEUGEBAUER, a citizen of Germany, and aresident of New York city, county and State of New York, have inventedcertain new and useful Improvements in Coin-Controlled X-Ray Apparatus,of which the following is a specification.

This invention relates to an X-ray apparatus so constructed that uponthe introduction of the proper coin the current will be conducted to thebulb, so as to effect an exposure for a predetermined period of time.The apparatus is actuated by the weight of the coin, whichupon` fallinginto a pan will swing a lever to make two contacts. The irst contactwill send the current through the bulb, while the second contact willplace in circuit a motor,.whioh at the proper time will tilt the pan,discharge the coin, and thus relieve the lever, which will return to itsnormal position.

In the accompanying drawings, Figure 1 is a front elevation of myimproved apparatus with the front removed; Fig. 2, a section on line 22, Fig. l; Fig. 3, a section on line 3 3, Fig. l; Fig. 4, a plan of theupper compart-` ment of the apparatus; Fig. 5, a section on v line 5 5,Fig. 4; Fig. 6, a section on line 6 6,

Fig. 5; and Fig. 7 a section on line 7 7, Fig. 45.

The letter @represents the case of an X-ray apparatus, of which ct isthe sight-opening, b the fluoroscope, a2 the opening for theintroduction of the object to be inspected, and c the bulb, all asusual.

d is the coin-slot, and d the chute which conveys the coin to a pan e,having, preferably, a perforation, so that coins of smaller dimensionsthan those desired will fall through without actuating the apparatus.The pan e is secured to a stem e', rotatable in a tubular two-armedlever f, fulcrumed tov a post lc4 at f2 and constituting a doublecircuit-closer. When the lever f is swung down at its pan end by theweight of the coin, two circuits will be closed. One of these circuitscauses the current to be sent to the bulb c, so as to form the X-rays,while the other current places in circuit a motor that will tilt the panand cause the discharge of the coin after the time set for theexhibition has ex pired. In this way the lever when released will rightitself, the contacts will be broken, and the apparatus will be set readyfor the introduction of the next coin.

The circuit for creating the X-rays is as follows: from battery g bywire g to induction-coil g2, wire g3 to post g4 and contact g5, thenceby contact-inakerf on end of lever f to contact gs, post Q7, and wireg8, back to the battery. The induced current will travel 6o as follows:from coil g2 to wire h, anode c', cathode o2, and wire h', back to co'ilg2. When the lever f is righted, the contact between the parts g5 gG isbroken by reason of the withdrawal of the contact-makerf, and thecurrent will cease to iow to the bulb o.

In order to tilt the pan c, I employ the following construction: Fromthe stem e of the pan e projects laterally an -arm e2, infiuenced by aspring e3. The arm e2 is adapted to be 7o engaged by'a pin or a roller ton the end of a crank-arm il', mounted on spindle This spindle isadapted to be driven by a train of gearing i from a motor 114, the trainbeing so arranged as to cause a ,complete rotation of 75 arm t" and aconsequent exposure for a predetermined length of time.

The operation is as follows: Upon the introduction of the coin and aconsequent tilting of lever f the latter will close contacts j] 8o andthecurrent will travel as follows: from a battery k to Wire la',rheostat k2, wire k3, post 204, lever f, contacts jj', wire kf', Vmotort4, and wire k6 to battery. The motor by belt n the motor it will bethrown out of circuit, and the crank-arm t" will be arrested until theapparatus is again set in motion by the introduction of another coin.

As an additional precaution against acturoo ating the machine by smallcoins, &c., the chute d' is slotted, as at d2, Fig. 6, so that willdrive the train i3 and the latter will rotate 85v such small coins willdrop through said slot and upon an auxiliary chute fm, that conveys themdirectly to the funnel Z.

What I claim is- 1. In a coin-controlled X-ray apparatus, thecombination of a lever adapted to be tilted by the Weight of a coin,with a pair of contacts adapted to be closed by the lever, one contactbeing adapted to place the bulb in circuit, and the other Contact beingadapted to place a motor in circuit, combined with means actuated by themotor for dislodging the coin, substantially as specified.

2. In a coin-controlled X-ray apparatus, the combination of a lever witha tilting pan carried thereby, a motor adapted to be placed in circuitby the turning of the lever, and

means actuated by the motor for tilting the pan, substantially asspecified.

3. In a coin-controlled X-ray apparatus, the combination of a lever witha spring-actuated tilting pan carried thereby, an arm movable with thepan, a motor adapt-ed to be placed in circuit by the turning of thelever, and means actuated by the motor for engaging the arm and tiltingthe pan, substantially as specified.
